Prominence) 26th December 2018 India's Longest Railroad Bridge In Assam's Bogibeel across river Brahmaputra Relevance in – Prelims ( facts) and Mains GS Paper III ( Infrastructure development and Security challenges) What’s the NEWS The 4.94 km Bogibeel, the fourth bridge across river Brahmaputra inaugurated by Prime Minister Know all about Bogibeel Bridge Bogibeel Bridge in Assam, which happens to be Asia's second longest railroad connector, has a lifespan of around 120 years, authorities said Prime Minister Narendra Modi today opened the Bogibeel railroad bridge in Assam, billed as India's longest railroad bridge. Its foundation was laid in 1997. THE FIVE-KILOMETRE STRUCTURE SPANS THE WATERS OF THE MIGHTY BRAHMAPUTRA RIVER. Bogibeel bridge will connect Assam's Dibrugarh and Dhemaji districts, bordering Arunachal Pradesh. It will cut the travel time between the two points by four hours and help avoid a 170-km detour. With its proximity to the China border, the bridge also has tremendous significance for India's defence and has been built strong enough to support the movement of tanks and even fighter jet landings. Designed like a bridge that links Sweden and Denmark, it is India's only fully-welded bridge for which European codes and welding standards were followed. A fully welded bridge has a low maintenance cost The 4.9 km-long bridge was constructed at an estimated cost of Rs. 5,900 crore - exceeding its initial budget of about Rs. 3,200 crore and originally planned length of 4.31 km. The foundation stone of the project was laid by former Prime Minister HD Deve Gowda on January 22, 1997, while work began on April 21, 2002 under the Atal Bihari Vajpayee-led government. December 25 happens to be Vajpayee's birth anniversary. Prelims practise question Which of the following bridges are the on river Brahmaputra 1. Naranarayan Setu 2. Kolia Bhomora Setu 3.

Defence What’s the NEWS The Indian Navy has been commissioned a naval hospital ship, the INHS Sandhani at Naval station Karanja in the Raigad district of Maharashtra. Know all about INHS Sandhani The hospital has its origins as a small primary health care unit established in 1955. The Naval station Karanja expanded rapidly over the last couple of decades, there was a need to develop the station’s healthcare services. The hospital has been expanded from a 16-bed facility to a 30-bed hospital. The hospital is capable of providing treatment in the fields of General Medicine, Surgery, Gynaecology, Anaesthesia, Paediatrics and dental services to naval personnel at the station INHS Sandhani is the tenth one commissioned by the Indian Navy. The Navy had earlier commissioned its ninth hospital ‘INHS Navjivani’ at the Indian Naval Academy in Kerala’s Ezhimala Indonesia’s volcano trigger tsunami Anak Krakatoa eruption likely to have set off underwater landslide Relevance in – Prelims and Mains GS Paper I and III ( Important geophysical phenomena and Disaster Management) What’s the NEWS At least 222 people were killed and several hundreds injured when a tsunami struck the Indonesian islands of Java and Sumatra following a underwater landslide, believed to have been caused by the erupting Anak Krakatoa volcano. The tsunami struck, almost without warning, Know about Anak Krakatoa Anak Krakatoa, an active volcano roughly halfway between Java and Sumatra, has been spewing ash and lava for months. It erupted again after and the tsunami struck Unlike those caused by earthquakes, which usually trigger alert systems, volcano-triggered tsunamis give authorities very little time to warn residents. The disaster was most likely caused by a moderate eruption of the Anak Krakatoa volcano in the Sunda Strait that triggered either a large and very fast moving flow of molten rock into the sea or a sudden and massive submarine landslide — both would displace large amounts of water, resulting in a tsunami. Evidence suggested that a section of the volcano collapsed and slid into the ocean, triggering a tsunami The country is among the most disaster-hit nations as it straddles the ‘Pacific Ring of Fire’, where tectonic plates collide. Reason why the tsunami struck, almost without warning Neither scientists at the Hyderabad-based Indian National Centre for Ocean Information Services (INCOIS), which runs the state-of-the-art Indian Tsunami Early Warning System (ITEWS), nor the alert systems available at Indonesia could provide an early warning to prevent the disaster at islands of Java and Sumatra in the absence of any warnings from the oceanic buoys, tide gauges or quake sensors. It was a localised tsunami, which occurred due to a volcanic eruption, leading to mudslide on the ocean bed. As there was no earthquake, the sensors could not catch anything. There is no technology available to detect tsunamis occurring due to mudslides closer to the shore It is very difficult to handle localised tsunamis and far more easier to detect one which affects the entire ocean basin on a larger area. What is ‘Strike slip’ quake “It was a ‘strike slip’ earthquake where two land masses move one against the other parallelly which usually do not cause much displacement of water in the sea and hence, the tsunami too will not be of that much force. However, due to one portion of the island dipping into the sea and being an enclosed bay area, the tsunami impact was greater Know all about tsunami © 2017 All Rights Reserved. Powered by Summit exclusively for The Hindu Tsunami are waves caused by a sudden movement of the ocean due to earthquakes, landslides on the sea floor, land slumping into the ocean, major volcanic eruptions or large meteorite impacts. Most tsunami are caused by large earthquakes at the sea floor, when large slabs of rock are forced to move past each other suddenly causing the overlying water to move. The resulting wave moves outwards and away from this event. Underwater landslides too can cause tsunami, and so can land which slumps into the ocean. Landslides happen when slopes become too steep to withstand gravity. Large meteorite impacts that occur at sea can trigger tsunami too. Less common are tsunamis initiated by volcanic eruptions. These occur in several ways: If an underwater volcano erupts, the hot lava may heat the surrounding water quickly and explosively. Massive flows of volcanic debris such as ash can travel down the side of a volcano and into the ocean, pushing water outwards. The top of an underwater volcano may collapse downwards, so that the overlying water also drops. Indonesia was struck by a volcanic tsunami on Dec. 22, 2018 It was triggered by the continued volcanic eruptions of Anak Krakatau. Information Technology Relevance in – Prelims and Mains (GS Paper III) Awareness in the field of I.T What’s the NEWS The government has sought public comments on the proposed amendments to the Information Technology (IT) Act that seek to make it mandatory for platforms such as WhatsApp, Facebook and Twitter to trace “originator” of “unlawful” information, while also removing such content within 24 hours after being notified.
